To all whom it may concern.-

Be it known that I, OLIVER H. ROBERTSON, a citizen of the United States, and a resident of Forestville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Cattle Stanchions, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

My invention relates to the class of devices used for securing an animal in any desired place, as in a stall or the like; and the object of my invention is to provide a device that may be cheaply constructed, as from wood, and one that shall at the same time be comparatively light and extremely strong and durable. 7 Referring to the drawings, Figure 1 is a view in elevation of my improved stanchion. Fig. 2 is a detail side view, on enlarged scale, of the joint formed at the meeting ends of the pivoted neck-bar and upper cross-bar, with parts broken away to show construction. Fig. 3 is a detail top view of this part of the device. Fig. 4 is a detail View, in vertical section, through this part of the device. Fig. 5 is a detail side view of the above-described parts, but showing a modified form of the invention. Fig. 6 is a detail top view of the modified form of catch and catch-plate shown in Fig. 5. Fig. 7 is a bottom View of the same. Fig. 8 is a detail view showing the construction of the joint for uniting the rigid neckbar with a cross-bar, with parts broken away to show construction. Fig. 9 is a detail view in elevation in plane at right angles to plane of view of Fig. 8, showing a construction of this joint. Fig. 10 is a detail view showing a preferred form of construction of the above joint in connection with the bottom cross-bar. Fig. 11 is a detail bottom view of the yokeplate.

In the accompanying drawings my improvement is shown as adapted to that form of a stanchion which is made up as a frame and suspended from a suitable support by a flexible connection, like means being employed at the bottom for limiting the swinging movement of the stanchion as a whole. In said drawings the letter (t denotes the top crossbar of a stanchion, b thebottomcross-bar or its equivalent, 0 the neck-bar, which is rigidly secured to the two cross-bars, and d the pivoted neck-bar of the stanchion, these several main parts of the frame being preferably of wood joined at the corners by improved fastening means.

The neck-bar dis pivotally connected at one end to the bottom cross-bar b, as by means of a pivot-bolt connecting Lthe parts, and a spring-latch secured to the upper end of this neck-bar is adapted to engage a catch a on the cross-bar a.

The spring-latch 6 comprises a base-plate or fixed member and a movable member or latch proper. The latch is provided with two proj ectin g branches 0 8 forming shoulders which are adapted to lie on opposite sides of the neck-bar cl and to rest upon the upper surface of the cross-bar a when the latch is engaged with the catch. Pivots (2 extending from these arms, overlie the upper surface of the cross-bar and form a support which aids in holding the frame parts more rigidly connected. A socket e is formed in the latch for the reception of the catch a, the front end of which is beveled, so that as the neck-bar is closed into place the swinging member of the latch is lifted by contact with the catch, rides over it, and by the force of a spring 9 is closed down upon it. The latch is provided with an arm a that engages the spring and normally holds the swinging member closed in position to engage the catch c. The pivotpin c has a bearing in each sidewall of the fixed member or case f of the latch, which is secured to the neck-bar d. A spring g is located in a recess formed in the case f, with one end seated against the bottom of a pocket and the other against the fixed arm 0 on the latch, thus holding the latter down upon the base or the shoulder d on the neck-bar d. The front end of the latch is preferably turned upward to form a cam or inclined surface to aid the automatic engagement of the latch with the catch a in the closing swinging movement of the neck-bar d.

In the form of my improved latch shown in Figs. 5, 6, and 7 the latch-plate 1 has two flanges 2 and 3 projecting from its under surface and adapted to lie against the opposite sides of the neck-bar d, 011 the top end of which the latch is secured. The flange 3 has a hooked end 4, turning toward and fitting into a crosswise recess or socket in the side of the neck-bar, thus providing an extremely firm means for connecting the latch to the end of the neck-bar and enabling it to be readily and firmly held in place, as by means of a screw secured near the outer edge of the bar, as illustrated in Fig. 5 of the drawings. In the plate 1 a recess 5 is formed for the reception of the heel of the movable member of the latch, the ears 6 on opposite sides of the recess forming supports or bearin gs for the pivots 7 of the latch in recesses in these ears. On the under surface of the latch a spring 8 is 1ocated,with one end thrust against the end wall of the recess and the other against the heel of the latch in such manner as to hold thelatch normally closed down upon the latchplate.

The neck-bar c is secured to the top cross bar a, and bottom cross-bar b by means which provide an extremely strong and durable joint and also permit of the lateral adjustment of the neck-bar with reference to the cross-bars,

so that the space'between the bars may be made of a variable width, as desired. The swinging neck-bar, which bears the latch, is

of course fixed in its position with reference I to the cross-bars, and all of the adjustment of the width between the neck-bars is accomplished by means connected with the fixed neck-bar c. In the preferred form of joint a clamping bolt it extends from the socket made edgewise in the neck-bar near its end, substantially parallel to the plane of the bar and through sockets in the cross-bar, which may slide in contact with the end of the neckbar. In order to strengthen the hold of the clamping-bolt, a yoke-plated (see Fig. 11) fits upon the end of the neck-bar and between it and the cross-bar, with holes 7?, through which the two members of the clamping-bolt pass, and preferably with short side flanges which fit down upon the front and rear surfaces of the neck-bar. A series of parallel holes are formed through each top and bottom cross bar near the end and registering, so that the neck-bar 0 may be properly joined at both top and bottom.

In the form of my improvement shown in Figs. 8 and 9 the cross-bar is provided with a lengthwise shallow mortise 0?, formed in the inner side of the cross-bar, near the end, to receive the end of the neck-bar, and this form may be used in lieu of the anchor-plate. The same form of clamping-bolt h is employed with both forms of socket; but the preferred form is that shown in Figs. 10 and 11.

By the use of my several improvements an extremely rigid and durable stanchion is provided, and it is obvious that as to the clamping-bolt the two vertical members may be formed in one piecethat is, in U shapeor may be formed of two separate parts, the bent end of the bolt extending into the opening or socket through the end of the neck-bar. By securing the latch on the upper end of the pivoted neck-bar, with the end in position to be easily held by the finger or thumb, means are provided for readily unlocking or locking the pivoted neck-bar and at the same time swinging it with the one hand which manipulates the latch. In an old form of structure where the latch is borne on the cross-bar of the stanchion one hand must be used for unfastening the latch and the other for swinging the neck-bar, an objection which is overcome by my within-recited improvement.

I claim as my invention- 1. In combination with a pivoted neck-bar of a stanchion, a case secured to the neck-bar and having flanges located on opposite edges of said bar, means independent of the flanges for preventing movement of the case, a latch pivoted in the case, and a catch for engaging the latch.

2. In combination with a pivoted neck-bar of a stanchion, a latch-casing secured to the neck-bar and having flanges located on opposite edges of the bar, a lip extending from one of said flanges into a groove in the bar, a latch pivoted to the casing and a catch for engaging the latch.

3. In combination in a loosely-suspended stanchion having top and bottom cross-bars and a rigid neck-bar connecting them, a neckbar pivoted at one end to one of said crossbars and having at the opposite end a shoulder engaging the upper surface of the crossbar when the parts are engaged, whereby longitudinal strains are resisted, and means for temporarily securing the pivoted neck-bar to the upper cross-bar.

4.. In aloosely-suspended stanchiomin combination, upper and lower cross-bars, a neckbar pivoted to one of said cross-bars and adapted to be temporarily secured to the opposite cross-bar by means of a latch, the latch, and a neck-bar secured to said cross-bars and forming one member ofa jointincludinga U shaped bolt extending along opposite sides of the neck-bar into openings depthwise through the cross-bar, said neck-bar projecting into a mortise extending lengthwise along the inner face of the cross-bar, and means for holding the bolt in position.

5. In combination in a loosely-suspended stanchion having top and bottom cross-bars and connections between said bars including a pivoted neck-bar, a latch-case secured to the pivoted neck-bar and having a shoulder adapted to overlie the top of the top cross bar' whereby longitudinal strains are resisted, and means for temporarily securing the pivoted neck-bar to the upper cross-bar.

6. In a loosely-suspended stanchion in combination, upper and lower cross-bars, a neckbar pivoted to one of said cross-bars and adapted to be temporarily secured to the opposite crossbar, one of said cross-bars having two sets of openings depthwise through the cross-bar, the openings in a set being equally spaced with respect to an opening in the op posite set, and a neck-bar secured to said cross-bars and forming one member of a joint IIS including a U-shaped bolt extending through the neck-bar and projecting along opposite edges, the branches being arranged to fit the openings through the cross-bar, whereby adj ustment of the cross-bar and neck-bar with respect to each other is permitted and means for holding the bolt in position.

7. In aloosely-suspended stanchion,in combination, upper and lower cross-bars, a neckbar pivoted to one of said cross-bars and adapted to be temporarily secured to the opposite cross-bar, and a neck-bar secured to said cross-bars and forming one member of a joint including a U-shaped bolt projecting through the neck-bar and extending along opposite sides thereof, the end of the neck-bar projecting into and fitting a mortise of a shape to prevent turning movement of said parts with respect to each other in the cross-bar and each end of the U-shaped bolt projecting through a hole depthwise through the crossbar, and means for holding the bolt in position.

8. In a loosely-suspended stanchion,in combination, an upper cross-bar having a mortise in its under surface at one end, and a recess at its opposite end, a bottom cross-bar having a mortise at one end and a neck-bar pivoted at its opposite end, a latch-case secured to the pivoted neck-bar and having a latch adapted to engage a catch on the upper crossbar, and the neck-bar adapted to engage and fit the mortises in said cross-bars, said mortises and bar being of a shape to prevent relative turning movement of the two parts and said bar forming one member of the joint between said parts, each joint including a U- shaped bolt projecting through the neck-bar and extending along opposite sides thereof and through openings depthwise through the cross-bar, and means for holding the bolt in position.
